CC3120: RadioTool unable to connect to custom board based on CC3120R BoosterPack

Part Number: CC3120
Other Parts Discussed in Thread: UNIFLASH, , CC31XXEMUBOOST

Hi,

I need to use the Radio Tool in order to test the performance of my design and improve the antenna matching. My design is based on the BoosterPack, I'm using UART to connect (RX, TX and nHIB).

Uniflash connects successfully and after flashing the Service Pack 3.7 (sp_3.7.0.1_2.0.0.0_2.2.0.6) I manage to connect to the AP and the webserver works nice.

I'm using the Radio Tool 1.0.2, and so far the app doesn't connect to it. I've tried tying RTS and CTS also but no change. 

Am I missing some connection or I need to flash a different version of the Service Pack? The RadioTool doc (SWRU471) point me to the wiki ()  but I get a permission error (

I'd appreciate your support.

Thanks in advance!

    Hi Kevin,

    Thanks for the quick reply!

    I've done it already, I'm using the CC31XXEMUBOOST, and as I described, the access to the wiki where the right version of the ServicePack is described is closed.

    Could you confirm which binary (service pack) should I program on the CC3120 flash?

    Best,
    Daniel.

    Hi Daniel,

    Oh I see. Can you try the service pack in the 1.40 SDK plugin for me? www.ti.com/.../1.40.00.02

    I think that one should match up with the latest Radio Tool update.

    Best,

    Hi Kevin,

    I've haven't had the chance to give a try to the 1.40 SDK yet, but I've found what my issue was:
    Although the Radio Tool gives the option of connecting over UART (it is the recommended method on the swru471 doc), and the connection works when the UART is used to flash the CC3120 attached memory, the communication between the CC3120 and the Booster pack is done over SPI (+IRQ line).
    Some initial interaction happens over UART (I believe for some sort of addressing when more than one CC3120 is connected to the BoosterPack), the commands and data are going through SPI.

    I'm using already the SPI interface on my application board, so I've used some API calls from the "Network Terminal" example app from the "simplelink_msp432_sdk_wifi_plugin_1_30_00_03" to perform the CW configuration I needed for my test.

    So, as a recommendation for anyone wanting to use the Radio Tool on a custom board I could add:

    1) Preferably use SPI for the interface with the MCU (don't forget the IRQ line and nHIB or Reset). It can go much faster than UART.

    2) Consider to add some test-points to expose the SPI lines if you need to use the RadioTool for development or production testing.

    Thank you!

    All the best,

    Daniel.
